"The mountains are calling, and I must go." —John Muir

Scary shit

Coming around a corner, I felt a shimmy through the front of my bike. I straightened up out of the turn to bring the bike under control. A second or two later I catapulted over the handlebars. The rim of my front wheel had completely detached from the hub. I had not hit anything — not another rider, a curb or even a rock. I landed on my head and broke my shoulder.
